ToiaZZ whom it may concern;

Be it known that 1, CHARLES O. PA MER, a citizen of the United States of America, residing at Cleveland, inthe county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Reels for Mine-Locomotives; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable ,others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in reels, for mine-locomotives, and has for its object to provide a simple reel for a gatheringlocomotive whose winding and unwinding of the wire thereon shall proceed automatically 7 without attention from the driver.

My invention relates more especially to reels operated by friction-controlled winding -mechanism and is in the nature of an iny provement on the reeledrive shown in In patent fora motor-car, No. 609,043, of Au st 16, 1898. In many of these locomotiv s as now devised it is necessary for the driver to shift a reel-lever from time to time in order that the reel-driving mechanism may be engaged properly to wind the wire onsaid reel. in the absence of such attention the winding mechanism works improperly and the cable that is'to be wound on the reel is run over by rate insulated wires or a twin cable are generally used,"'and a cross connection between the wires would be considerable damage, and

every precaution should be takento avoid it.

These insulated wires are quite expensive,

and the cost-of their occasional renewal is a drawback to the use of the reel, although its advantages are very im ortant. I- endeavor to overcome. this draw ack b making the winding and unwinding depen on the movement of the locomotive and independent of.

the attentions of the driver. The principal use of these reel lo'comotives is in making up the train for the heavier locomotives which haul the train along the mine-entries to the tipple. They operate in the mine-rooms where there is'- no trollc -'-wire,and owing to the limited use ofthe track it is of the cheapest kind of construction. The gathering locomotive moves alternately forward and.

backward at vvry irequent intervals and into rooms in every direction, so that the said reellever requires irequent attention.

The same characters designate the san parts throughout the several views.

The car-frame m is mounted on wheels a and isdriven by electric motors m, geared to the axles in the ordinar Way. In order to allow forrtlie inequalitiesof the track, the frame is mounted on springs'in the usual manner. The reel, which is mounted on the frame, is preferably wound up by a driving connection in train with the car-axle. In order that the distance from center to center of sprocket-wheels shall be nearly constant when running over a rough track, an inter mediate shaft '0 is placed in the frame on a level with the axle, and the winding of the reel is done through it. Such a driving-train isshown in Figs. 1 and 6.

Referring now to the reel shown in the first six figures, the convo'yer-reel it" turns loosely on the reel-shaft '0", which is journaled in the -frame u which in minis bolted tothe locofriction-disk "1) and engaging sakl ratchetteeth is the pawl n. The said sprocket wheel is driven by a chain from the interme- Between the Fig. 3 is a vertical Pivoted on ,the' I Y diate Sllatil/ i), which in turn is driven by a chain from the motor-shaft, as shown in Fig. 1. The ratchet-teeth on the sprocket-wheel are pointed iuthe direction necessary to en'- gage the pawl to wind up the cable when going backward; but the pawl slips when the locomotive is moving in the opposite direction and the cable .11 is being paid out. On the other end of the reel (see Fig. and pivoted to the reel-frame 11. is the pawl m, that engages the ratchet-teeth formed on the friction-dis a. The ratchet-teeth on the disk to are pointed in the direction to engage the pawl n and prevent the friction-disksmovmg back ard when the reel is being unwound. IVhen the reel is being wound up, the pawl n slips. a

The amount of friction on the reel is regu lated by the nut v on the reel-shaft u and is made sufficient to give the requisite pull on the electric cable that is wound thereon and is enough to wind it up properly, and so keep.

it from being run over as the car backs toward the, entry. As already stated, one ratchet is engaged when the wire is unreeled and the locomotive is moving away from the entry, and the other ratchet is engaged when the car is moving toward the entry, so that one or the other ratchet is engaged all the time, and when oneis engaged the other slips. Both ratchets allow for the same direction of positlve rotation of the frietiondisks, that direction being the one in which to wind up the cable.-

In Figs. 6, -7, 8 are shown a horizontallyrevolving reel embodying my invention.-

'.l.hc'rce1 1L rests on the friction-disk n, the weight -alone supplying the necessary friction to give the cable the required tension. The frictiondisk n is attached toratchet disk n", which is'providedwith ratchet-teeth that engage the pawl m, pivoted on the 1000- motive-frame, andprevent its backward motion when the cable is being unwound. The said friction-disk is driven by shaft 'm (to which it is secured) bymcans of the gears m and m through the single acting jawed clutch 1h, the intermediate shaft v, and the sprocket-wheel m, then through a chain from a motor axle or shaft in driving connection therewith. All of said gears and sprocket-wheels are secured in their respective shafts except ear m, that revolves loosely and is provi ed with'teeth that engage the'teeth of the clutch-jaw m, that is splined on shaft m. The said clutch-teeth. drive the reel only when winding up the ca bl'e. When the gear m moves in the opposite direction, the clutch-jaw m slides out of enga erncnt and the gear m slips on its shaft.

' The action of pawl m in Fig. 8 is the same as pawln in'Fig. 5enamely, to prevent the friction-disk turning backward, but allowing it to be driven forward. Also the action of the clutch m with gear mfof Fig. 7 is the I have not gone into the matter of the electrical details, nor have I shown the meclr anisin for guiding the cable on the reel, as these may be of any suitable construction well known in the art and do not form part of my invention. the construction shown in Fig. 6 the cable may be guided invarious directions by idle pulleys situated on the frame as may be desired. I i

In my invention I prefer to have the-reel geared to wind on the wire faster than the locomotive moves, the friction allowing the reel to slip, so that the wire receives only the requisite tension.

although other forms =may be usedwithout departing from the nature of the invention.
